Spacing problems with 2.9.21 (as opposed to 2.8)

[Arvid Grøtting]

Hi!

I'm completing a score that I think shows a bit of regression with
newer 2.9 versions as opposed to 2.8.  The problem is that the spacing
gets a bit weird, giving 7 pages with 2.9.21 when only 5 is needed
with 2.8.

The .ly file (and two include files) and resulting output can be
viewed at

    http://regina.uio.no/~arvidg/Badn_lat.pdf

(Convert-ly only changes the \version header here.)

For some reasons, 2.9.21 has three systems per page on all pages,
while 2.8.1 has three on the first page and four thereafter, but I
don't know if that's a symptom or the problem.  Also, 2.9.21 breaks
one line itself (in addition to the manual \break commands), but that
could be to fill out all the pages for all I know.

Anyway, is this a bug?
